Express powers amendment
Governor Otter (Idaho) has requested the Idaho state legislature to pass a resolution to the federal government to initiate two amendments to the Constitution of the United States that would better define the powers of the federal government vis-à-vis the states and the people.
The first would amend the Tenth Amendment to read as follows: (Changes in quotes): "The powers not “expressly” delegated to the United States by the Constitution, nor prohibited by it to the States, are reserved to the States respectively, or to the people. “This amendment shall be considered by all federal courts as a rule of interpretation and construction in construing any case involving an interpretation of any Constitutional power claimed by the Congress under either the "interstate commerce" or the "necessary and proper" clauses of Section 8, Article I.”"
The second would amend the Interstate Commerce Clause (Article I, Section 8) as follows: (Changes in quotes): "To “directly” regulate Commerce with the foreign nations, and among the several States, and with the Indian Tribes, “with no authority in Congress to regulate matters that are primarily intrastate with only an insignificant or collateral affect upon interstate commerce”".
Wyoming has passed a version of the resolution and it is being promoted within the Western Governors Association.
